to valve mechanism, for sausage staffer-s ut s m? My invention relates especially applicable used for fillingsausage casings, ployable in other relations.

It is the object ofmy invention to provlde novel means operating upon the handle end of the valve-plug for, maintaining the valveplug in its and, iurthe'r, tov provide such valve-plug with a passage which s round and of as great'area in, cross-sect on as the passage in advance of andifollowing "said passage "in the valve-plug.

It is the" ObJectof my invention, further,

tioned comprising a valveplug which is re-- inovable in novel mannerjfor-readily cleaning the passage used for feeding the meat in a sausage'stufler, and the various inner parts of the valve; further, to provide novel means a. for readily assembling the valve-plug inzits valve-seatand for removing the same,- turtherfto provide novel means for-adpisting a conical valve-plug otithe, character nientionedin its valve-seat, and for maintaining such adjustments; Y and, further, to provide novel yoke nieans for securing the valveplug in its seat, which formsstops for the valve-handle for left-handed and righthanded operations of the latter. 1

The invention will be'furtheri readily un-' derst'ood frond the following description and claims, and from the drawings, in which latter? v Fig. 1 represents a plan view-of nyinoproved devicein connection with so much of a sausage stalling machine as is necessary 'Fi'gl 2 is a vertical section ofthevsame, taken on the'line'22of Fig.1. j v f 'Fig. 3 is a cross-section'of the same, taken in the plane of the line3-3 of Fig; 2, and. including theyoke. 1 4cis a'horizontal section, taken in the plane of the line 2, showing'the Iiig.- 5is asimilar view, showing the valve m d a Fig. 6 is a vertical cross-sectional"detail,

A port-iom of the pressure casing of 'Ta usualsausag e stufiing machine is vexemplified at 11*. i The" casing comprises a usual "cylindrical wall 12, at the upper end" of which there is "a" removable eoverf13.

The nipple is provided with a discharge passage-j 26, and; the valve-casing'iwitlrpas- ,sage's'27 r spectively in advance of and-fol lowing the. valveeplug. ,Thenozzle is pro-1 videdwitha dischargepassag'e 28'. T Avalve- I plug 29'is; in the valve-casing and is represented as aconicalivalve-plug seated in a conical valve-seat 30 ofv the valvebasing. It is provided 'With a passage '31 {The passages 27 are cylindrical.

The pa s sage T 31 "is .also preferably of-cylindrical form and of a diaineteras greatas the di- 1 ameters of the passages 27 and-of the passage26 and in line'with. saidpassages, so that the fiow. of the *rn'aterial "through the valve isnot constricted or changed indirecg tion, thereby savingpowerapplied in shuding theinateria-l;

In' Lmy lm'proved' device I provide the valve-casing with lateral bulges, asshown at 33, for enabling me 'to provide a conical valve-plug which has a passage of cylindrical formand of a diameter'as' greatias'the assages in'the valve-casing, and'for accomm odating'the side walls 346fsaid' passage in the valve-plugandifoi' providing such sidewalls sufficiently large to close the passages "in the valve-casing, the widths of the narrowest portions of said" side walls being f substantially equal a to :the diameters of -sai'd passages; 'i (Compare Eigs. 2,'4 and 5.") Ifh'ave provided'fmezmspfonreadily dismantling the valve, so that all of the passages maybe readily cleaned, which is an important feature in machinery of the character exen'iplified. 7

Thus I provide a yoke 37, which comprises side arms 38 having bearings 89 pivoted on shoulder screws 40, threaded into lugs 41 at the outside of the outwardly bulged portions 33 ot the valve-seat;

Means, are provided between the yoke and the valve-plug for securing the valve-plug in the valve-casing and for adjusting the valve-plug in its seat, Thus the yoke ex? tendsfabove the axis of the valve-plug and hasa screw 44 received through a threaded.

place for proper seatingofthe valve-plug in the valve-seat.

The screw may, be unthreaded in its threaded bearing out of its se'at 48, whereupon the yoke may be swung away from the valve-plug,so that the valve-plug is readily removable from its seat, and ready access providedto allthe passages and the valveplug, for readily and thoroughly cleaning the same. y r When the valve-plug is replaced, the yoke is returned to obstructing position and the screw screwed toward the valve-plug, for seating it in its valve-seat, the nut limiting this inward movement for locating the valveplug in its seat in correct position for readily turning the same and preventing leakage 1 between the valve-plug and its seat.

7 I preferto provide-means for securing the nut in ad usted positions, exemplified as a set-screw 5 1, having threadedconnection 'Wlt'h' the nut, and impinging: the set screw for securing the nut in adjusted positions for properly reseating the valve-plug "on replacementsof thesaine. i i

The valve-plug isprovided 'with a handle 53, bymeans of which itmay beopened and closed, means being provided'for permitting the handle to be'swimg to. the left or to the right for either lefthanded or right-handed operation, limiting means being: provided 'for limitin-g' the movements of the valveplugtoward the right and t-owardthel'eft at positions 'at which its'passage is in line with the passages of the valve-seat.

'For' this purposerI provide the yoke with recesses '54, thefrecesses being shown formed by rearward bends in the respective sides of the yoke,'t-he upper arms of the yoke receding'in the direction of: the valve-passages, and the side-arms; otthe yoke having bends formed by'said bends, the side arms thus forming stops, as shown by the'dotted positions of the handle in Fig, l, tor locating the valve in extremely open positions. The recesses also provide clearance spaces for the valve-plug when removing the latter.

My improved" device forms an exception ally strong valve mechanism of great capacity for ready flow ofthe prepared sausage meat from the sausage stufl'e'r tothesausage casing, in the exemplification stated, provides convenient means tor'ready access-to and cleaning of the valve mechanism, provides for ready" adjusting and maintenance ofadjustments forthe valve-plug, 'and'ready means for left-hand and right-hand operations of the same. a I a 1 Asthe valve-plug wears, the' screw 44 may beturned for firmly reseating the valveplug in its valve-seat, the nut '49 beingifix ed in a new location" for the-new adjustment.
